Abstract
A semiconductor integrated circuit including on the same semiconductor substrate: a first circuit block including a switching transistor which is off when the first circuit block is inactive and on when the first circuit block is active, the first circuit block including internal circuits adapted to provide predetermined functions, the internal circuits being connected to a first power line maintained at a low-level source voltage; a second circuit block including internal circuits adapted to provide predetermined functions, the internal circuits being connected to a second power line maintained at a low-level source voltage; a power line switch section connected between the first and second power lines; and a control circuit adapted to control the power line switch section so that the first and second power lines are connected together at a later timing or gradually over a longer period of time than the switching transistor turns on.
